Produktbeschreibung
High-performance LiFePO4 under-seat battery for mobile and stationary energy systems
The ULTIMATRON ULM-48-100H is a compact lithium iron phosphate battery with a 51.2 V nominal voltage, 100 Ah capacity, and 5120 Wh energy. The flat under-seat housing allows for space-saving integration. The battery is suitable for high-performance 48 V energy systems, autonomous solar installations, special-purpose vehicles, and professional energy storage. Additionally, this model features an integrated heating function. It starts automatically when charging current is applied below 0 °C, enabling charging in extreme environmental conditions down to -35 °C.
The integrated Smart BMS monitors the battery cells and protects the system against overcharging, overvoltage, and overheating. Important battery data can be monitored in real time on a compatible smartphone or tablet via the integrated Bluetooth 4.0 connection.
